TANK-HEATEl-.

SPECIFICATION forming part of Letters Patent No. 6355224, dated October 17, 1899.

Application iled March 11, 1899.

T0 all whom t wuty concern.-

Be it known that I, JOHN H. BENNEY, a citrzen of the United States, residing at Evansville, in the county of Rock, State of VVisconsin, have invented certain new and useful Improvements in Tank-Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved tankheater and to means in connection therewith for the heating of water, boiling of feed, dac.

Tank-heaters, broadly considered, are not new and have been used in the northwestern sections of this country as a means for preventing water from freezing in tanks either for household purposes or for the watering of stock; but the heaters which have been suggested heretofore are expensive to construct and are wasteful of fuel. By means of my present improvement I provide and produce a device which is of simple construction and which therefore can be built very cheaply and one wherein a great amount'of radiating-surface is obtained, whereby a material saving in fuel is obtained. In my improvement I also provide means for the heating of water, boiling of feed for stock, dto., the object being to keep the water in the main tank at the proper temperature for drinking purposes for the stock, while the water or feed in the auxiliary tank, which I shall hereinafter describe, can be maintained at any temperature desired and actually boiled or cooked, if necessary.

For a better comprehension of my invention attention is directed to the accompanying drawings, forming a part of this specification, and in Which- Figure l is a side elevation of the device; Fig. 2, a plan view thereof; Fig. 3, a longitudinal sectional view, and Fig 4 a cross-section taken on the lines a: :c of Fig. l.

In all of the above views corresponding parts are designated by the same letters of reference.

The body A of the improved tank-heater is made, preferably, of cast metal of the general shape or configuration shown, it being generally cylindrical for its main part, with the sides a d extending tangentially to the Serial No. 708,658. (No inodelJ able or permanently secured in position. The

cylindrical casing C extends, preferably, to a point a short distance from the interior walls of the body A, so as to form an annular chamber or flue c between it and said body A. The cylindrical casing C is provided with openings d therein a short distance from the bottom thereof and through which the products of combustion pass. Said openings are arranged, preferably, in a horizontal line and are by preference formed only in that part of the casing C that is farthest removed from the stack e, formed in the top of the body A, whereby the products of combustion will be caused to pass entirely around said casing C before reaching said stack.

D is an air-supply pipe leading from the top of the body A and opening into the casing C at its lower end. A fire is to be built on the bottom of the tank-heater within the casing C. The products of combustion pass through the openings d d, so as to heat the walls of the body A and the air-supply pipe D, and thence pass to the stack e, said re receiving a supply of heated air through the air-pipe D.

Mounted within the upper open end of the cylindrical casing C, so as to prevent the escape of the products of combustion from said cylinder, is an auxiliary tank E, having a contracted lower portion f, which fits tightly within the casing C, and with a flange g,which rests upon the top of the casing C. This auxiliary tank E is provided with an ordinary cover h. In addition to preventing the escape of the products of combustion from the cylindrical casing C the said auxiliary tank can be used for the reception of feed, which may be cooked therein by the heat from the fire within said casing, or said auxiliary tank may be used for the heating of water or for other purposes.

When my improved tank-heater is to be IOO used in cold weather, a fire is built on the bottom of the same Within the easing C, and the auxiliary chamber E is placed in position at the upper end of said casing and is filled with feed or Water. The device is now placed Within the tank or trough, in which is placed drinking-water for the stock or for other purposes, and the heat imparted to the Walls of .the body A by the products of combustion of the fire passing through the openings d (l and coming in contact with the walls will maintain the Water in the tank or trough at the temperature desired for drinking purposes. At the same time the feed or water in the auxiliary tank E Will be acted upon by the heat of the fire.

Having no\v described my invention, what I desire to secure by Letters Patent isl. An improved tank-heater, comprising a body A of a general cylindrical shape with the sides a extending tangentially therefrom so as to form a projecting portion, a stack e in said projecting portion, a cylindrical casing C extending down Within the main portion of the body A, to the bottom thereof and in which a lire is built, openings d, d, in said casingat points therein farthestremoved from said stack, through which openings the products of combustion pass to the said stack around the sides of the casing C, an air-supply pipe D extending down from the top of said projecting portion, adjacent to the stack and the bottom of said casing, and supplying heated air to the ire therein,and a cover for the said casing, substantially as set forth.

2. An improved tank-heater, comprising a body A of a general cylindrical shape, with the sides a extending tangentially therefrom so as to form a projecting portion, a stack c, and an air-supply pipe D in said projecting portion,a cylindrical casing C extending down Within themain portion of the body A, to the bottom thereof and Within which a ire is built, openings d, d, in said casing near the bottom thereof at points therein farthest removed from said stack, through which openings the products of combustion pass t0 the said stack around the sides ofthe casing and the pipe D, to the stack e, and a cover for said casin g, substantially as set forth.

3. An improved tank-heater, comprising a body A of a general cylindrical shape with the sides a extending tangentially therefrom so as to form a projecting portion, a stack c in said projecting portion,'a cylindrical casing C extending down within the main portion of the body A to the bottom thereof and in which a fire is built, openings d, d, in said casing at points therein farthest removed from said stack through which openings the products of combustion pass to the said stack around. the sides of the casing C, an air-supply pipe D extending down from the top of said projecting portion adjacent to the stack to the bottom of said casing and supplying heated air to the fire therein, and an auxiliary tank E having a contracted portionfmounted within the upper part of said casing and having a flange g which rests above the body A, substantially as set forth.

This specification signed and witnessed this 9th day of February, 1890.
